Assay typeEnzyme activity
Abcam MMP9 Inhibitor Screening Assay Kit (Fluorometric) (ab139449) is a complete assay system designed to screen MMP9 inhibitors using a quenched fluorogenic peptide: MMP Fluorogenic Substrate Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH2 [Mca=(7-methoxycoumarin-4-yl)-acetyl; Dpa=N-3-(2,4-dinitrophenyl)-L-α-β-diaminopropionyl]. Mca fluorescence is quenched by the Dpa group until cleavage by MMPs at the Gly-Leu bond separates the two moieties. The assays are performed in a convenient 96-well microplate format.
This kit is useful to screen inhibitors of MMP9, a potential therapeutic target. The MMP inhibitor NNGH is also included as a prototypic control inhibitor.

FunctionMay play an essential role in local proteolysis of the extracellular matrix and in leukocyte migration. Could play a role in bone osteoclastic resorption. Cleaves KiSS1 at a Gly-
-Leu bond. Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide.
Tissue specificityProduced by normal alveolar macrophages and granulocytes.
Involvement in diseaseIntervertebral disc disease
Metaphyseal anadysplasia 2
Sequence similaritiesBelongs to the peptidase M10A family.
Contains 3 fibronectin type-II domains.
Contains 4 hemopexin repeats.
DomainThe conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.
modificationsProcessing of the precursor yields different active forms of 64, 67 and 82 kDa. Sequentially processing by MMP3 yields the 82 kDa matrix metalloproteinase-9.
N- and O-glycosylated.
Cellular localizationSecreted, extracellular space, extracellular matrix.
- Information by UniProt
